API key not valid for this application

I just started using graphhopper and I am using Indonesia-latest.osm.pbf. However, when I tried the web ui, I received “API key not valid for this application.” The same case happened with other pff file (europe-germany-berlin.pbf). Just wondering what is going on here, thank you.

You can run the GH maps demo locally without this problem, still the tiles will block on a server. See this deployment guide.

My local GH server is running on a VM (guest).
I’m trying to use it from the host and I get the same error.
Any hint would be appreciated.
